Prepare the Vegetables. Cut the cherry tomatoes in half and finely chop the lettuce. Set both aside while you prepare the dip.

Make the Taco Dip Base. In a large mixing bowl, combine the softened cream cheese, sour cream, and taco seasoning. Stir until everything is well blended and the mixture is smooth and creamy.

Shape the Christmas Tree. Spoon the cream cheese mixture onto a large serving platter and spread it into a Christmas tree shape. For a neater look, you can use a piping bag to outline the tree first, then fill in the center and smooth it out with a spatula.

Add the Lettuce and Cheese. Sprinkle the chopped lettuce evenly over the tree, leaving the bottom section uncovered to resemble the trunk. Next, add a layer of shredded cheese over the lettuce.

Decorate the Tree. Arrange the halved tomatoes, cut side down, and sliced black olives over the cheese to resemble Christmas ornaments. Space them out so the decorations are visible.

Add the Star Topper. Using a star-shaped cookie cutter, cut a star from a slice of orange cheese. Carefully place it at the top of the Christmas tree.

Serve the Dip. Arrange tortilla chips around the platter or serve them in a separate bowl for dipping. Keep the dip refrigerated until you're ready to serve.
